Lumileds Luxeon V, test of a 4000K 70CRI emitter

Thanks for the test djozz. Need to get you some samples of XP-L2. I’d donate to the cause. Impressive that the 4000k Luxeon V has almost identical output to a 6500k SST-40, and at a lower voltage to boot. Tint looks wonderful too! Can’t wait for some high CRI and more color temps.

How much does a custom run of DTP copper boards usually cost?

…and :+1: :+1: :+1: Lumileds of course.

Very interesting LED.
Maybe start a ‘groupbuy feeler’ thread.

But Djozz, how off is the size for an XM board?
Looks as if it could fit just as good bad as on an XP board…

The Luxeon V will not fit XM-boards at all.

I just posted over on RMMs thread to see if he has any plans to stock the Luxeon V and perhaps even get some custom DTP boards made up for it. He has his MTN Quad boards which are top notch, so if he did a Luxeon V board I would be in for quite a few. A triple or quad Luxeon V board would be really interesting as well.

Wow! Nice job on this test!

Exciting. If Vf's get a bit lower, one could nicely buck drive 4S emitters with 4S cells.

Thank you for another great contribution to the hobby.

16mm DTP

8) 8) :sunglasses:

When will they be on your website? I’d like a few of those.

Send me your address to PM, I wanted to send you a few anyway.

:+1: PM sent. I will do a new Luxeon V test on this boards and am really curious how much different it is. My guess: slightly better performance but way easier reflow!!

Have you tried a Luxeon V in a flashlight yet and if so, what is your experience?

Will that be for sale on your website soon? Looks good! Really want to see this emitters potential on a properly sized board.

Thank you very much Sir!

Another test that saved my wallet…

I plan to use this LED to my DIY host zoommy, because It has almost round LED.

@djozz

I'll build Convoy S2+ with LD-A4 this weekend

@Jensen567

Yes, I'll put boards on my web page very soon.

Hey Neven,
Nice board!
Will you have the LEDs for sale too?

Hope that the boards and a high bin Luxeon V will be available in your shop. Can not wait to do a Q8 mod with this leds on DTP boards!

Nobody dedomed it yet?
I’m really interested in whether it throws better than SST-40…

As mentioned in the OP, my predictions for the luminance gain after dedoming (if at all it works) are not good, this being a flip-chip design.

I think it could be interesting in triples and quads, though it depends on the actual die size.
